The Dow notched record after record this year, blowing past 14,000 for the first time in February. The index of blue-chip stocks smashed 15,000 in May, 16,000 in November. Tuesday's new record closing high marked its 52nd for the year.

The year’s rally was fueled partly by the Fed’s monumental stimulus program, known as quantitative easing.

The central bank announced this month that it would begin gradually scaling back its $85 billion in monthly bond purchases that have kept interest rates low but have sent investors clamoring for returns in riskier vehicles such as stocks.

“We’ve had a government shutdown and debt-ceiling debate that brought us to the edge of default and the stock market didn’t care,” said Jack Ablin, chief investment officer at BMO Private Bank. “For the most part, Wall Street shrugged it off."
